Design of Compatibilizing Interfacial Polymer Layers Using a Macroinitiator
. Immobilization of an amine-containing peroxide macroinitiator APM onto solid mineral surfaces has been achieved via physical/chemical adsorption of its macromolecules from solution. A systematic variation of reaction parameters upon graft polymerization initiated by surface-attached APM including nature of monomer and solvent has been conducted. The effect of solvent and nature of monomer on the overall constant of polymerization, effective activation energy, initiation efficiency as well as other parameters of elementary stages of the process has been established. It has been revealed that the involvement of TiO2 particles with the surface-attached radicals in the heterogeneous polymerization process profoundly influenced all the elementary stages, particularly chain transfer and termination.
